• the active substances which can be used according to the invention intervene in the metabolism of the plants and can therefore be used as growth regulators.
• Plant growth regulating substances can be used, for example, to inhibit the vegetative growth of the plants.
• Such inhibition of growth is of economic interest, among other things, for grasses, since it can reduce the frequency of grass cuts in ornamental gardens, parks and sports facilities, on the side of roads, at airports or in orchards. It is also important to inhibit the growth of herbaceous and woody plants on the side of the road and in the vicinity of pipelines or overland lines or in general in areas where a strong growth of the plants is undesirable.
• growth regulators it is also important to use growth regulators to inhibit the longitudinal growth of cereals. This reduces or completely eliminates the risk of the plants twisting ("storing") before harvesting. In addition, growth regulators in cereals can cause stalk reinforcement, which also counteracts storage. The use of growth regulators for stalk shortening and stalk reinforcement makes it possible to apply higher amounts of fertilizer in order to increase the yield without the risk of the grain being stored.
• An inhibition of vegetative growth enables denser planting in many crops, so that additional yields can be achieved based on the soil area.
• An advantage of the small so obtained Another plant is that the crop can be processed and harvested more easily.
• Inhibiting the vegetative growth of the plants can also lead to increased yields in that the nutrients and assimilates benefit the bloom and fruit formation to a greater extent than the vegetative parts of the plants.
• Growth regulators can often also be used to promote vegetative growth. This is of great benefit when the vegetative parts of the plant are harvested. A promotion of vegetative growth can also lead to a promotion of generative growth at the same time, in that more assimilates are formed, so that more or larger fruits are formed.
• increases in yield can be achieved by intervening in plant metabolism without any changes in vegetative growth being noticeable.
• growth regulators can be used to change the composition of the plants, which in turn can lead to an improvement in the quality of the harvested products. For example, it is possible to increase the sugar content in sugar beets, sugar cane, pineapple and citrus fruits, or to increase the protein content in soybeans or cereals. It is also possible, for example, to break down desired ingredients, e.g. To inhibit sugar in sugar beets or cane, using growth regulators before or after harvest.
• the production or outflow of secondary plant substances can be positively influenced.
• One example is the stimulation of latex flow in rubber trees.
• Parthenocarpic fruits can develop under the influence of growth regulators.
• the gender of the flowers can also be influenced.
• Sterility of the pollen can also be produced, which is of great importance in the cultivation and production of hybrid seeds.
• the branching of the plants can be controlled by using growth regulators.
• the development of side shoots can be promoted by breaking the apical dominance, which can be very desirable, especially in ornamental plant growing, in connection with growth inhibition.
• the number of leaves in the plants can be controlled in such a way that defoliation of the plants is achieved at a desired time.
• defoliation plays a major role in the mechanical harvesting of cotton, but is also found in other crops such as of interest in viticulture to facilitate harvesting.
• Defoliation of the plants can also be carried out in order to reduce the transpiration of the plants before transplanting.
• the crop fall can also be controlled with growth regulators. On the one hand, premature fruit fall can be prevented. On the other hand, the fall of fruit or even the falling of the flowers can be promoted to the desired extent ("thinning") in order to break the alternation. Alternance is the peculiarity of some types of fruit, which endogenously produce very different yields from year to year. Finally, it is possible to use growth regulators at the time of harvest to reduce the forces required to detach the fruit in order to enable mechanical harvesting or to facilitate manual harvesting.
• growth regulators it is also possible to accelerate or delay the ripening of the crop before or after the harvest. This is particularly advantageous because it can be optimally adapted to the needs of the market. Furthermore, growth regulators can improve fruit coloration in some cases. In addition, growth regulators can also be used to concentrate maturity over time. This creates the conditions for, for example, tobacco, Tomatoes or coffee a full mechanical or manual harvest can be done in one operation.
• growth regulators can also influence the seed or bud rest of the plants, so that the plants, e.g. Pineapples or ornamental plants in nurseries, germinate, sprout or bloom at a time when they are usually not ready to do so. Delaying bud budding or seed germination with the help of growth regulators may be desirable in frost-prone areas to avoid damage from late frosts.
